Statement as of 12:11 PM CST on February 11, 2012
... A wintry mix still on tap for Sunday night into Monday...
A mix of wintry precipitation is expected across eastern Oklahoma
and northwest Arkansas late Sunday night... continuing into the day
Monday. Given the timing of the precipitation... some impacts are
expected for the Monday morning commute.
A fast moving storm system will move out of the Desert Southwest
late this weekend... resulting in precipitation development across
the Southern Plains. With cold air already in place... the
precipitation will likely begin as snow across eastern Oklahoma
late Sunday night... spreading into northwest Arkansas Monday
morning.
As the storm system moves closer to and over the area... temperatures
aloft will increase from southwest to northeast... which will cause
the snow to transition to sleet and/or freezing rain over a good
portion of the area on Monday. The heavier precipitation will be
ending from west to east starting around midday Monday... with
lingering areas of drizzle or freezing drizzle into Monday night.
The highest snow accumulations will likely occur near the Kansas
and Missouri borders... as well as in the higher terrain areas of
northwest Arkansas. At this time... it appears that 1 to 4 inches of
snow and sleet accumulation is likely with locally higher amounts
possible. There is also the potential for some minor ice
accumulations to the south of the heavier snow band. Prolonged power
outages or similar major ice impacts are not expected.
Persons should continue to monitor the latest forecasts as snow
and ice amounts continue to be refined through the weekend. A
Winter Storm Watch may be needed for some areas late Sunday night
into Monday.
